Title: Production of superconducting substance
Inventor: KONISHI FUMITO
IPC: C04B35/00
Filed: 1987-08-08
Abstract: PURPOSE:To provide a superconducting substance in a desired form by obtaining a sol state and gel state from a soln. and by heat-treating when rare earth element-Ba-Cu-O oxide superconducting material is produced. CONSTITUTION:For example, Y alkoxide, Ba alkoxide and Cu alkoxide, Cu acetate or Cu formate are dissolved in alcohol such as methanol in the molar ratio of 1:2:3. The soln. is placed in a beaker made of resin, the mouth of the beaker is covered with wrap and several holes are perforated in the wrap to prevent from locally proceeding the hydrolysis of these alkoxides. At that time, impurities such as precipitate are possibly observed and in this case, however, it is necessary to dissolve them by adding diluted hydrochloric acid, etc. Or, the soln. may be heated below the b.p. of methanol. The hydrolysis together with polycondensation proceeds by allowing to stand the soln. in the beaker to obtain its sol state. The sol is spun by pulling up a glass rod from the sol and the fibriform gel obtd. is heated to obtain fiber having the composition YBa2Cu3Ox.

IPC: F28F19/00
Filed: 1987-08-11
Abstract: PURPOSE:To prevent a reduction in heat exchanging performance of a heat exchanger and lengthen its service life by disposing a baffle plate which is wetted with water or other fluid in the inlet passage of air flow carrying dust. CONSTITUTION:When a refrigerating machine is being operated, the air flow A passes through a baffle plate 2 to enter into an evaporator 1 where it exchanges heat with and cooled by cooling medium flowing in a heat transmission pipe 1a through the heat transmission pipe 1a and fins 1b. Moisture contained in the air, then, is condensed on the surfaces of the heat transmission pipe 1a and fin 1b to become liquid, which flows down into a drain pan 3. Said condensate is splashed onto the baffle plate 2 by a rotating disc 4 to moisten the supporting member 2a and fins 2b. Dust contained in the air flow is adsorbed by the condensate on the surfaces of the support member 2a and fins 2b and is collected on the baffle plate 2. This way, dust is removed from the air flow coming into the heat exchanger by the baffle plate 2 before it enters into the heat exchanger.

Title: Overcurrent preventing circuit in motor driving circuit
Inventor: NISHIJIMA HIDEO
IPC: H02P6/06
Filed: 1981-12-14
Abstract: PURPOSE:To improve the irregularity of the hFE of various drive transistors and to prevent the overcurrent by negatively feeding back the currents of the transistors to a control amplifier and providing a limiting circuit at the input level of the control signal to the amplifier. CONSTITUTION:Since the currents of drive transistors 3, 4 are all flowed through resistors 10, the irregularities of the hFE of the transistors 3, 4 can be improved by negatively feeding back the variation in the voltage produced at the resistor 10 to an amplifier 11. The maximum current at the normal operation time depends upon the resistance component of a power source 9 and a drive coil 1 or 2. Accordingly, even when the controlled voltage Vin which exceeds the variation in the voltage of the resistor 10 produced by the maximum current is inputted to an input terminal 5, the overcurrent can be prevented even when the coil 1 or 2 is shortcircuited by setting the reference power source 13 so as to conduct a limiter diode 14, and is limited into the maximum current value.

Title: Freezing cycle
Inventor: KAMIKURA MASAKAZU
IPC: F25B39/02
Filed: 1991-08-09
Abstract: PURPOSE:To make equal pressure difference of each of capillary tubes and reduce a pressure loss in a system in which a plurality of multi-tube type heat exchangers piled up therein have some capillary tubes are provided by a method wherein a length of each of the upper stage capillary tube, middle state capillary tube and lower stage capillary tube is made different from each other. CONSTITUTION:Refrigerant gas compressed by a compressor is liquefied by a condensor 2 and dispersed by a distributer 3. The dispersed liquid refrigerant flows into each of multi-tube type heat exchangers 7 to 9 through each of capillary tubes 4 to 6. The liquid refrigerant is heat exchanged with brine to form its gasified state and then the gasified refrigerant is returned back to the compressor 1. A difference in height between the capillary tubes 4 and 5 is defined as H1, a difference in height between the capillary tubes 4 and 6 is H2. Comparison of pressures P4 to P6 of each of the capillary tubes 4 to 6 gives a relation of P4>P5>P6. Replacing these values with refrigerant circulating amounts g4 to g6 of each of the capillary tubes 4 to 6 gives a relation of g4<g5<g6. In order to eliminate a difference in refrigerant circulating amounts, a capillary length is made short from the lower stage to the higher stage in compliance with a height difference.

Filed: 1988-08-11
Abstract: PURPOSE:To unnecessitate a deceleration device and to perform an accurate setting of resistance by a method wherein a resistor and/or a sliding element is driven by the force of an ultrasonic motor. CONSTITUTION:A sliding element 2 is pressure-bonded on a stator 3 which performs ultrasonic ellistic vibrations, the sliding element 2 (the rotor of an ultrasonic motor) receives turning torque by the ultrasonic elliptic vibrations of the stator 3 through the intermediary of friction force, and it is driven at a low speed.
